BBC program The One Show was taken off air mid-broadcast last night, after a fire alarm sounded twice during the show, interrupting an interview with actress Tamsin Greig.

Presenters Alex Jones and Matt Baker remained unfazed by the alarm, which could be heard twice as well as an announcement not to use the lifts whilst evacuating the building, preceeding to complete a link to a VT.

An edition of Nigel Slater's Simple Suppers cookery show was played during the remainder of the time the show should have been on air.

Responding to worried viewers of the show on her twitter account, Jones revealed the modest cause of the alarm, writing: "We're all safe and well!!! Somebody was warming their tea up and the microwave set off the fire alarm! That's live telly for you!"

A BBC spokesperson confirmed there was no fire, apologizing to viewers from the disruption and stating normal service was resumed promptly.
